Waterproofing mid-to-large vertical equipment conduits on complex metal roofing profile panels presents severe design challenges. Standard rectangular flashing plates often face physical limitations when adapted to tight cylindrical structures or dense multi-pipe penetrations, as geometric stress distribution along corner sections frequently causes premature separation. Under continuous thermal stress and fluctuating weather conditions, traditional sealing systems experience localized fatigue, creating gaps that permit moisture infiltration.

The YS-28 engineering matrix resolves these industrial vulnerabilities by implementing a specialized circular footprint optimized for pipeline outer diameters from 6" to 11" (150 mm to 280 mm).

Advanced Material Properties & Geometric Engineering

The mechanical stability of the YS-28 framework focuses on delivering uniform radial loading alongside continuous structural defense:

Dual-Compound Configurations: Formulated in weather-stable EPDM or thermal-grade Silicone. The EPDM base guarantees high resistance to ultraviolet exposure and atmospheric ozone cracking, while the Silicone option retains persistent flexible properties under continuous hot exhaust operations up to 240 degrees Celsius.

Technical Specifications

Product Model: YS-28

Applicable Pipe Range: 6" to 11" (150 mm to 280 mm)

Base Plate Diameter: Diameter 368 mm

Material Configurations: Premium EPDM + Aluminum / Silicone + Aluminum

Quality Control and Installation Principles

Maintaining a reliable, permanent perimeter seal with the YS-28 system depends entirely on strict installation steps. Installation teams must accurately measure and cut the stepped rubber cone to an aperture roughly 10 percent smaller than the target conduit diameter to ensure continuous compression. 

Frequently Asked Question:
What mechanical advantage does the Diameter 368 mm circular base of the YS-28 provide over a traditional square base?
The round profile eliminates structural corners where stress typically concentrates. This evenly distributes thermal expansion loads and wind uplift forces across the assembly, significantly reducing the risk of edge lifting and sealant failure on undulating roof claddings.
